The stock MAP sensor(2 BAR) is the same for any turbocharged or supercharged GM model. Look for late 80's 4 cyl turbo Sunbirds or 91 and later S/C Park Ave/Bonnevilles. The 3 BAR was only used on the TTA. The knock module is turbo SFI Buick only. The 87 is different than the 84-86. I cant remember the difference but there have been a couple of post about it so you might try do do a search unless they got deleted during the last couple of months.
